In June Guardian Australia revealed that the last of the detainees on Nauru were being moved off, although that detention centre will be kept open at a cost of $350m a year.
According to the most recent statistics for July, released in September, there were still 37 detainees on Christmas Island’s north-west point immigration detention centre.
But an Australian Border Force spokesperson said it “can confirm that the final transfer of immigration detainees from Christmas Island to the Australian mainland has occurred”.
